Longevity parameters and water content of Secale cereale seeds stored at 35 °C, after equilibration at 75% RH and 20 °C. Deterioration is expressed as the time for seed germination to decrease to 75, 50, and 20% of initial germination. Data are expressed by mean values ± standard error. n = 4 replicates of 25 seeds each.
